Be it known that l, DUNCAN ti. a citizen of the llouiinion of Cap-mm ingat Vancouver, in the Province 0) Columbia, Canada, have invented new anduseful Improvements in (Free Atomizers and Air-l /lixere oiwhieli lowingis aspecification.

This invention. relates to 9. burner wherein the oil is etomiz oughlymixed'with t required 11 bustion before delivery to the but i This isaccomplished by delivery as required onto the vanes off :1 I ugal fan bywhich-the is oi'ew'u iu delivered to the burner, the ten i". leg 5 at ahigh speed of rotation. by en nd ent motor, preferably a turbine di jetof Water from the domestic Water service The invention is particularlydescribed in the following specification, refere being made to thedrawings which. it is eeeo' peeled, in. which:
